Compatibility 802.1X and mac-filter from ACS

I am assuming you are asking if you configure a x mac of wlan client in MAC filer and the same as user naem in 802.1x ACS database as user name , could you configure it ? what is the effect?

If my understading of your queston is correct the answer is

Any wlan client will not be allowed to associate to the network unless a match is seen in mac filter in wlc.

But once that is done it will not able to access network resources unless 802.1x authentication is completed by ACS against the wlan clients user name which is again a mac address of client.

i dont see a value for doing this. except that you will block unnecessary authentication request getting to ACS by filtering it in the 1st instance.

another scenario is if you are using mac filtering also on ACS , it should be preceeded by mac filtering and then ACS authentication , as above as far as ssequence goes hence the same logic applies here.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.
